Calvert [57] ABSTRACT A sheet sleeping-bag provided with openings for accommodating the neck, head and arms designed to prevent a person from leaving the bed and throwing off his bed clothes, while ensuring an optimal lying position, the sleeping-bag being stitched onto a drawsheet by means of at least one piece of fabric, said drawsheet being in turn fastened to a bed, and where said piece of fabric is formed as a triangle, one side of which is stitched onto and along portion of the centre line of the back of the sleeping-bag with the second side thereof being stitched onto and along portion of the centre line of the drawsheet, and where the third side of the triangle extends from the centre line of the drawsheet up towards the centre of the sleeping-bag.

6 Claims, 3 Drawing Figures l SHEET SLEEPING-BAG BACKGROUND OF THE INVENTION The present invention relates to a sheet sleeping-bag of the type which is closed at the top except for hole edges defining openings adapted to accommodate the neck and arms of a person disposed therein, and which is designed to prevent the person from throwing off his bed clothes or crawling out of bed without preventing the person from lying down in any desired position.

Norwegian Pat. No. 73,716 discloses a childrens bed dress or retaining girdle of the type having a bodice, the lower end of which only is secured to a reinforced band on the centre portion of the back, and which, except for its centre portion, is further secured to a rectangular piece of fabric such that the portion of the rectangular piece of fabric disposed between the points of attachment on the reinforced band bulges upwardly from the back of the bodice and extends into the front portion thereof, whereby it will be lying loosely over the child. The band and the lower portion of the rectangular piece of fabric have further been provided with tapes for attachment, for example to a bed. However, the use of such a bed dress or retaining girdle involves the disadvantage to the effect that the child does not possess its full freedom of movement to lie down on its side, but is forced to assume a position of lying down on its back.

Danish Pat. No. 96,637 discloses a blanket adapted to be attached to the surface of a bed, where at either side the upper edge of the blanket is secured to a piece of fabric which is substantially shorter than the marginal length of the blanket so as to create between the points of attachment a wide gap between the blanket and the centre portion of the piece of fabric. A bodice is secured to the centre portions of the upper edge of the blanket and that of the piece of fabric. In order for a child retained in such a girdle to have its full freedom of movement to lie down on its side, the bodice must be fastened by means of tapes, bands or the like. It is a well-known fact, however, that the use of tapes and the like should be avoided, particularly in connection with children as they may be both dangerous and inconvenient.

The object of the present invention is to provide a sheet sleeping-bag designed to prevent a person disposed therein from throwing off his bed clothes or crawling out of bed, and which will nevertheless allow full freedom of movement to lie down on the side, stomach or back without the use of tapes or similar retaining means, and without impairing safety.

The sheet sleeping-bag according to the invention is characterized in that it is stitched onto a drawsheet by means of preferably a triangular piece of fabric, said drawsheet being attached, for example to a bed.

This has the advantage that, without impairing safety, a person disposed therein is allowed full freedom of movement to lie down or be placed in a convenient and desired position on his side when resting or sleeping. A person placed so as to lie on his side furthermore will not be exposed to suffocation by saliva, vomiting or the like as easily as a person forced to lie on his back.

One embodiment of the sheet sleeping-bag according to the invention is characterized by one side of the triangular piece of fabric being stitched onto and along the centre line of the back of the sleeping-bag and the second side of the triangle along the centre line of the drawsheet, while the third side of the triangle is disposed between the lower end of the sleeping-bag and the centre line of the drawsheet.

This has the advantage that a person disposed therein is allowed full freedom of movement to lie down on his side, stomach or back, but is prevented from sitting up.

A further embodiment of the sheet sleeping-bag according to the invention is characterized by one side of the triangular piece of fabric being stitched onto and along the centre line of the sleeping-bag and the second side of the triangle along the centre line of the drawsheet, while the third side of the triangle is disposed between the upper end of the sleeping-bag and the centre line of the drawsheet.

This has the advantage that a person disposed in the sleeping-bag is allowed to sit up, while retaining his full freedom of movement when lying down.

A further embodiment of the sheet sleeping-bag according to the invention is characterized by the size of the sleeping-bag being designed to fit children.

This has the advantage of allowing the sleeping-bag to be used in cots, perambulators and the like.

These and other objects and advantages of the present invention are more particularly set forth in the following detailed description of preferred embodiments and in the accompanying drawings.

DESCRIPTION OF DRAWINGS FIG. 1 is a side view of one embodiment of the sheet sleeping-bag according to the invention,

FIG. 2 shows a second embodiment of the sheet sleepingbag according to the invention, and

FIG. 3 is a frontal view of same.

DESCRIPTION OF THE EMBODIMENT SI-IOWN HEREIN Referring now to FIG. 1, reference number 1 is a side view of a drawsheet onto the centre line of which there is stitched a single triangular piece of fabric 2 in perpendicular relationship, said piece of fabric being further stitched onto the centre line of the back of a sleeping-bag 3.in perpendicular relationship. As indicated on the drawings said sleeping-bag has at the top-end thereof hole edges defining openings for the arms and the neck to accomodate a person to be placed in said sleeping-bag. This embodiment of the invention is designed to retain a person lying down and allowing him full freedom of movement to turn over on his side, stomach or back, while preventing the person from rismg.

In a second embodiment of the sheet sleeping-bag, the bag may be stitched on in reversed relationship, as shown in FIG. 2, i.e. turned This will enable a person disposed therein to sit up, but he is still prevented from standing up completely or crawling out of bed.

In FIG. 3 the sleeping-bag 3 is viewed from above with the drawsheet l disposed therebelow, and where the triangular piece of fabric 2 is indicated by dash lines. An alternative embodiment adapted to further retain the person lying in bed and which allows less freedom of movement consists in using two triangular pieces of fabric either alone or in combination with the said triangular piece of fabric, as shown by dotted line and designated 2a. The lower surface of the drawsheet is provided with diagonal tapes 4, to the corners of which rings 5 are attached to enable the sleeping-bag to be fastened to a bed or similar piece of furniture. Along the line x-x the sleeping-bag has a zipper (not shown), and the top of the neckband may be closed by means of a button and buttonhole loop (not shown). This means of closure makes it an extremely easy matter to place a person in the retaining girdle, and at the same time it has been so positioned that, for example, a child will not be able to open it by itself or be bothered thereby. Tapes, belts and the like, which may be both dangerous and inconvenient, have been completely eliminated. In said embodiment the neck-band is circular but may, of course, be square too or otherwise formed.

The sheet sleeping-bag according to the invention may be used in connection with patients in nursing homes or institutions but is particularly suitable for small children. The fabric and size should as a matter of course conform to the intended application.

The invention is not restricted to the abovementioned embodiments and may be modified in many ways without departing from the scope of the inventron.
